The Cleanest Whey Isolate Available
NutraBio 100% Whey Protein Isolate is scientifically designed to provide 25 grams of protein that's a clean and pure source of protein derived solely from 100% Whey Protein Isolate — which research has shown to ignite muscle protein synthesis, promote optimal nitrogen retention, and accelerate muscle growth and repair.
Our high-quality Whey Protein Isolate contains no whey concentrate or other inferior proteins and no amino spiking, added carbs, maltodextrin, dextrose, creamers, or any other fillers — just pure cross-flow ultra-filtered, non-denatured whey isolate protein supplements.
Why choose Whey Protein Isolate?
Muscle Growth
No other macronutrient is more essential to muscle growth and recovery than protein. Unfortunately, not all whey protein supplements are created equal. The most beneficial and fast-digesting form is whey protein isolate which contains not only branched-chain amino acids but also all the essential amino acids as well. Whey protein isolates are more easily digested and absorbed by the body to help achieve rapid muscle recovery and growth. NutraBio 100% Whey Protein Isolate provides the purest source of protein available (90% whey isolate protein).
Such a high level of purity can only be achieved through a cold cross-flow micro- and ultra-filtration process that removes the larger, less-absorbable protein molecules while also filtering out fat and lactose. Furthermore, this process does not denature the valuable proteins and peptides in whey, so the protein boost itself is of a higher quality to help further enhance muscle growth.
Muscle Recovery
Studies suggest ingesting fast-acting protein sources, such as a whey isolate protein powder, can increase amino acid levels in systemic circulation and stimulate robust increases in protein synthesis, arguably the most important physiological factor in existence when it comes to muscle recovery and growth.
Moreover, since high-quality isolates and the use of an iso protein powder are generally low in carbs, lactose-free, fat-free, cholesterol-free, and gluten-free, it makes it the perfect choice for low-carb dieters, lactose intolerant individuals, or athletes who want to get ripped while packing on muscle. You get no digestive issues compared to inferior protein supplements and better recovery thanks to 25 grams of protein per scoop and all your essential amino acids.

FAQs
Frequently Asked Questions
When is the best time to take NutraBio 100% Whey Protein Isolate?
We suggest consuming one serving immediately post-workout when your body is in need of critical nutrients to maximize muscle protein synthesis, which ultimately leads to muscular growth and recovery. It can also be consumed between meals to meet daily protein requirements.
Is consuming too much protein bad for your kidneys?
Absolutely not. This is a myth. There is no scientific literature that shows that eating a high-protein diet has any detrimental effects on renal function in otherwise healthy individuals.
How should I stack NutraBio 100% Whey Protein Isolate with your other products?
We suggest taking one of our versions of PRE 30-45 minutes before your workout, Intra Blast during, and 100% Whey Protein Isolate immediately after.
Can't I meet my daily protein requirements through a regular diet?
While it is possible to meet daily protein requirements through a balanced diet, some individuals find it difficult to get the 1.5-2 grams per kg of body weight necessary to maximize muscle growth and promote recovery. This is why individuals often turn to whey protein supplementation as a convenient way to meet their individual protein needs.
Are whey isolates superior to higher quality whey concentrates such as WPC 80?
Yes and no. Whey isolates are 90% pure protein, while higher quality whey concentrates will be ~80% pure protein, making isolates “superior” on a gram-for-gram basis. However, both forms of whey digest rapidly and help support muscle-building and recovery goals. At the end of the day, which one you choose really depends on your goals. If you need a protein that is lower in calories and free of fats, lactose, and cholesterol, go with an isolate. On the other hand, if you need a protein that is more calorie dense and fat-laden, which may be beneficial when weight gain is the goal, choose a high-quality whey concentrate. Just be sure the label makes clear that the whey concentrate being used is at least 80% pure protein.
